I LHMQAW I QQS Q 6y ad/na e Unitgd States Patent BASE FOR USE WITH LUBRICATED SPINNING AND TWISTING RINGS Andrew J. Wayson, Needham, Mass., assignor to Merriman Bros., Inc., Boston, Mass, a corporation of Massacllusetts Application September '22, 1953, Serial No. 381,599 8 Claims. 01. 57 m This invention relates to the textile industry and is more particularly concerned with the art of spinning and twisting rings.

In the description of the invention that follows when reference is made to spinning rings, it will be understood that such term is also intended to cover twisting rings.

It has become common practice in the spinning and twisting ring field to provide means for causing continuous lubrication of the rings thereby to prolong the life of the travelers. In furtherance of the need for lubrication, there has been developed the so-called porous spinning ring which is made of powdered metal by known procedures. The powdered metal rings have a network of very small spaces therethrough which permits the absorption of a lubricant, generally oil, which thereafter oozes from the surface of the spinning ring to provide an oil film whichis picked up by the traveler as it moves about the ring.

Powdered metal spinning rings are customarily mounted on a base of special design which base includes an oil reservoir and means for transmitting the oil from the reservoir to the ring in proper quantity. If the oil reservoir is of adequate size, the refilling thereof may be held to relatively infrequent intervals. This is an important labor saving feature which will be appreciated when it considered that a typical spinning'mill will have many thousands of spinning rings.

It has also become common practice to use as means for supplying oil to the spinning ring a, wick, the ends of which are positioned in the oil reservoir and the body of which rests against part of the spinning ring thereby to cause movement of the oil from the reservoir to the ring. The rings bases and included wicks are customarily assembled in the ring manufacturers plant and if this work is properly done, the wick ends, will lie in the oil reservoir. However, due to the fact that the reservoirs in use up to the present have included metal covers with small hinged lids at one corner thereof, it hasnot been possible to determine visually. after the'ring and base have been assembledwhether in fact the wick is in proper position in the. oil reservoir.

Another disadvantage of existing constructions with metal covers on the reservoir is that it is not possible to determine visually whether additional oil is required. Instead, the hinged lid must be raised and some instrument inserted into the oil reservoir to determine how much is needed.

A further disadvantage of existing reservoir metal covers is that they are hinged in such manner that they are subject to breakage and bending in use with the re suit that the covers after a short period fit very poorly or are broken off. Textile fibers drift into the opening between the cover and the reservoirs with part of the fibers remaining outside. Capillary action causes oil to climb through the fibers to run down the outside of the reservoir. T his upsets oiling schedules as the capillary action will not be uniform at all of the rings on the ICC 2 rail. It also creates a very dirty ring rail and uncentamination. of yarn as the oil collects and drops from the edges of the ring rail. Furthermore, in the covers of the prior art metal projections have been provided that extend beyond the edge of the reservoir which may be grasped by the fingers to enable the cover to be opened. These projections have been found objectionable as they often catch the yarn as it goes back into operation after being pieced-up. V W

Accordingly, the present invention is designed to over-'- come these defects and to present additional advantages. The invention as hereinafter described and claimed scencerned solely with the base construct-ion and particularly the oil reservoir construction. The invention includes a transparent leak proof window sealed to the top of the reservoir whereby by visual inspection it can be deter mined if the wick ends are in proper place and whether or not additional oil needs to be added.

The invention also includes a self closing opening in the cover in which the spout of an oil can may be inserted at any time to replenish the oil supply. Upon re; moval of the spout, the opening will automatically be closed, thus preventing any surface leakage to.th e spin ning ring basewhich in turn results in unsoil'ed' work.

The invention also contemplates a transparent oil'reservoir window which may be readily replaced at low cost should the window be soiled to prevent visibilityor be.

otherwise damaged. I y

The visibility factor provided by the transparent window also assists the operator in determining if at any time improper oil has been put in the reservoir. When the baseis used withthe powdered. metal. type spinning ring,

c'ertaiiitypes of oils must be used for best results. U,r1dei'.

the former practice in which the interior of the oil rater-1 voir could not be seen, it often happened that incorrect oil was placed in the reservoir so that proper lubrication of the travelers would. not thereafter take place, Such failure was often attributed to the porous. powdered metal spinning ring instead of to the true cause, namely,

The present invention miiniinizes the improper oil. chance of this type of failure occurring.

The invention will be. more fully understood'by reference to the detailed description which follows'andthe accompanying drawings in which Fig. 1 is aplan view of a section of a spinning frame on which is mounted aspinningring base incorporatingthe present invention with a ring in position. thereon.

Fig. 2 is an enlarged cross section taken on the line 22 of Fig. 1-.

Referring to Fig, 1 the spinning ring. frame 2having.

the usual aperture 4 has mounted thereon a spinningring base 6-which carries a vertical type spinning ring 8. While a vertical ring is shown; it will be understood that he invention-may be used With-equal facility with thesecalled horizontal type of spinning-ring. The base 6 is anchored to the frame in the customary manner by screws 10 and 12 and the spinning ring 8 is likewise secured to I the base by the drive pins 14, the edges of which overlie the ring flange 16. A conventional traveler is shown at 13.

The ring flange 16 rests on the base supporting flange 20 which extends for a full circle under ring flange 16. Flange 20 has a small channel 22 therein which likewise extends circumferentially under flange 16. In this channel is positioned a wick 24 the ends of which pass through a gate 26 in the wall 28 which surrounds the exterior periphery of flange 16.

At the front of base 6 is an enlarged area which constitutes the oil reservoir 29 and into which the ends 30 and 32 of wick 24 extend and are shown as resting on the bottom thereof.

The general nature of the oilreservoir 29 is shown in Fig. 2 in which is disclosed a bottom 34, a front wall 36, a rear wall 38 and transparent cover 40. In addition, there are the end walls 42 and 44 shown in Fig. 1. The cover 40 fits snugly about its periphery in a rabbeted recess as indicated at 46 in Fig. 2. It is permanently secured in place by a plurality of drive pins 48 which are inserted in suitable bosses formed adjacent the reservoir.

. The cover 40 has a hole 50 therethrough in which is positioned a closure 52. This closure includes a flange 54 extending about its circumference which overlaps on the underside of the periphery of hole 50.

A compression coil spring 56 is positioned in cup 58 with its lower end engaging the bottom of the reservoir and its top the under side of closure 52. The spring normally maintains the closure in sealing engagement with the cover. Extending downwardly from the under side of closure 52 is a cylindrical portion 60 of suitable dimension to fit over cup 58 and to act as a guide for the vertical movement of the closure.

Visual inspection of the reservoir through the transparent cover 40 will suifice to advise the operator if oil is needed. In such case the spout of an oil can may be pressed against the top of closure 52 forcing it downwardly to a point, below the level of cover 40. Oil may then freely enter the reservoir until it is filled to the proper degree.. Removal of the oil spout will result in the closure automatically sealing itself.

If the cover 40 becomes soiled or damaged it may be removed by prying it upwardly with a suitable tool in which case the drive pins 48 will be pulled out without damage to be reused to secure the new window that may be inserted.

It is my intention to cover all changes and modifications of the example of the invention herein chosen for purposes of the disclosure which do not constitute departures from the spirit and scope of the invention.
